I understand the Glock booth gunsmith at local gunshows will install a Siderlock safety while you wait. As simple as they are to install (so I've read), any reputable local gunsmith should be able to install one.

Thanks for the comments. I shipped the Glock to Rick Devoid of Tarnhelm Supply in NH. I will do a follow up post when I receive it back from Rick.

As to why I wanted a manual safety. I carry IWB using a Clipdraw (there is an ongoing thread regarding that subject in Carry Issues Section) and was using the Saf T Blok trigger block behind the trigger. It functions as it should but is an external part that can be dislodged or lost. And it is hard to practice with because you have to look for it after every course of fire. I am accustom to a manual thumb safety and that is all (IMO) the Glock needed to meet my needs.

Can't you tell us more, post some close up pics? How long does it take? Did they do anything else? Does it look like a factory job? Does it complicate detail stripping?

It took a little over 2 weeks but Sandy may have caused a delay. It matches up perfectly with the slide release and looks like it came from the factory, very professional. I had Rick reinstall the factory trigger the aftermarket trigger was too light for a carry gun, in my opinion. I only field strip the gun for cleaning and it does not impede that process in anyway. I have not been to the range since I got it back but when I do I will give a report. One unusual feature is you must let the slide go forward under its own power. If you retard the foward motion of the slide the safety will not engage. I have a stainless steel guide rod and recoil spring and that may have something to do with it.

Is this a Tarnhelm Supply design, or do they use Siderlock?

It sounds like the ability to chamber a round by hand racking the slide has been lost. Thus, chambering requires locking the slide open, inserting a loaded mag and releasing the slide lock. Correct?

No, that is not what I am saying. 1. the gun has to be cocked.
2.You can rack the slide back with or without a magazine, with or without a round. When the slide is pulled all the way back let it go and everthing works as it should.
3. If you ease the slide forward with your hand is when it may not work.
